Re: [pacman-dev] [PATCH] Move cursor to the end of the screen at the SIGINT

It requires exposing 'move cursor to the end' function in a pacman header file. We use it as a chance to make naming of the cursor management functions more consistent.

Note that there is still possibility of a race condition in the cursor update logic. 'update cursor index variable' and 'send ASCII control symbols to console' is not an atomic operation. So if an SIGINT is received between these two action then cursor position is going to be screwed.

Fixes FS#67973

Looks good. As an aside, I'd like to boot those console functions into a separate file at some stage. Allan
